BENJAMIN J. MLLEN, OF LEETONIA, OHIO.

GAS-WASHER.

SPECIFICATION forming part of Letters Patent No. 782,042, dated February '7, 1905.

Application tiled July 8, 1904. Serial No. 215,775.

be it known that I, BENJAHIN J. MULLEN, a citizen ot the United States, residing at Leetonia, in the count)v of Columbiana and State ot' Ohio` have invented certain new and useful lmprovements in (asVashersg and ldohereby declare the following te be a full, clear, and exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to malte and use the same.

This invention relates to gas-washers `t'or use in connection with blast-furnaces; and it consists in the novel construction and combination ot the parts hereinafter t'ull5v described and claimed.

ln the drawings, Figure l is a vertical seetion through the gas-washer. Fig. Q is a partial sectional plan view ot' the same.

'lhe washing ot' the gas is etfected in a large vessel A. The lower partB of this vessel contains water, and is the outlet-pipe at the bottom ot' the vessel through which the water and dirt are removed periodically. This pipe is provided with any suitable valve tl is an overiiow-pipe and water seal arranged at about the level of the water in the washer, and c is the inlet or supplvY pipe for water.

l) the inlet-pipe for the gas, which is connected to the side of the washer and which conducts the gas into it t'rom the blast-furnacel is the entletpipe for the gas after being washed. The pipe E depends from the upper part otA the washer to within a short distance ot' the water-level, and it conducts the washed gas to the boiler or stoves, where it is used in the usual wav. The outlet-pipe E forms an annular chamber f inside the washer, and the lower part et' this annular chamber is divided into a series ot' smaller gas-chambers G. The gas is brought in contact with the surface otl the water as it issues from these small chambers ablyv consist ot' short open-ended pipes which are secured into plates H. These plates Hare arranged side by side and they t'orm an annular head at the lower part of the annular gaschamberf.

The small gas-chambers Gr )refer-i J represents angle-iron brackets t'or supporting the said plates. These angle-irons are secured to the vessel A and ,to the lower part ot' the outlet-pipe, so that the outlet-pipe is used as a support, and no additional means are necessar)v tor supporting the plates and the pipes or small chambers carried b v them.

The gas which enters the washer is divided into small volumes before being brought into Contact with the water, and this subdivision ot' the gas insures the whole ot' it being brought in contact with the water. 'lhe gas impinges on the surface otl the water as it passes out Ot' the small chambers or pipes and parts with its dust and other impurities, which are taken up bv the water. '.lhe clean gas passes between the short pipes and into the bottom ot' the outlet-pipe and thence upwardly to the boilers or stoves, as indicated b v the arrows in the drawings.

lVhat l claim isl. ln a gas-washer, the combination, with a vessel for holding water provided with an inlet-pipe, and an outlet-pipe which depends within the said vessel and forms an annular gas-chamber within it; otl a head supported at the lower part of the said annular gas-chamber, and a series ot' open-ended chambers carried by the said head and operating to divide the gas into simili volumes betere it touches the water.

2. In a gas-washer, the combination, with a vessel for holding water provided with an inlet-pipe, and an outlet-pipe which depends within the said vessel and t'orms an annular gas-chamber within it; ot' supports secured to the lower part ot the said inlet-pipe and to the said vessel, removable plates which rest on thc said supports, and a series ot' open-ended chambers depending from the said plates and operating' to divide the gas into small volumes before it touches the water.

In testimony whereof l have atlixed my signature in the presence ot two witnesses.

BENJAMIN J. MULLEN.
